UCFL205 pillow block bearings

UCFL205 pillow block bearings 1. Basic code (type code, size code, inside diameter code [2 digits])
The basic code is used to indicate the bearing’s inner diameter, diameter series, width series and type, generally up to five digits, which are first described as follows:
1) The bearing inner diameter is indicated by the first digit from the right of the basic code. For the commonly used inner diameter d=20 ~ 480mm bearing inner diameter is generally a multiple of 5, these two numbers indicate the bearing inner diameter size is divided by 5 quotient, such as 04 indicates d= 20mm; 12 means d = 60mm and so on. For bearings with an inner diameter of 10mm, 12mm, 15mm and 17mm, the inner diameter codes are 00, 01, 02 and 03. For bearings with an inner diameter less than 10mm and greater than 500mm, the inner diameter representation method is otherwise specified, see GB/T272-93.
2) The diameter series of bearings (that is, the change series of bearings with the same structure and the same inner diameter in terms of outer diameter and width) are represented by the third digit from the right of the basic code. For example, for radial bearings and radial thrust bearings, 0 and 1 indicate extra light series; 2 indicates light series; 3 indicates the middle series; 4 Indicates the heavy series. The size pairs between the series are shown in the figure below. In addition to the use of 1 to indicate the ultra-light series, the rest of the thrust bearing is the same as the representation of the radial bearing.
3) The width series of bearings (that is, the series of changes in the width of bearings with the same structure, inner diameter and diameter series) is represented by the fourth digit from the right of the basic code. When the width series is listed as series 0 (normal series) for the comparison of the diameter series in Figure 13-4, the width series number O is not indicated in the designation for most bearings, but for aligning roller bearings and tapered roller bearings, the width series number 0 should be indicated.
Diameter series codes and width series codes are collectively referred to as dimension series codes.
4) The bearing type code is indicated by the fifth digit from the right of the basic code (for cylindrical roller bearings and needle roller bearings and other types of code is a letter).
